SPRING-MOTOR.

SPECIFICATION forming part of Letters Patent No. 440,123, dated November 11, 1890.

Application filed Juno 26, 1890. Serial No. 356,913. (No model.)

To all whom it may concern:

Be it known that I, N IELs ANDERSON, a sub- I]ect of the King of Denmark, residing at Audubon, in the county of Audubon and State of Iowa, have invented certain new and useful Improvements in Spring-Motors; and I do declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which 1t appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked 1thereon, which form a part of this specificaion.

My invention relates to improvements in spring-motors; and the object of my improvement is to provide a spring-motor that will automatically wind its springs. I attain these Objects by the mechanism illustrated in the accompanying drawings, in which- Figure lis aperspective view of the entire machine, and Fig. 2 is a sectional view, taken on the broken line a: at, Fig. 1, of one of the springs, spring-barrel, and the shaft to which the inner end of the spring is secured.

Similar letters refer to similar parts throughout the several views.

The two longitudinal pieces a, the longitudinal pieces g and t, the two cross-pieces c, the two upright pieces m, and the two upright pieces d constitute the frame of the machine. The two sprocket-wheels E revolve upon the shaft G', and each has firmly secured to it a spring-barrel D, so that ywhen the spring-barrel revolves the sprocket-wheel secured to its end also revolves. Each spring- 'barrel D contains a coiled spring F, having its outer end secured to the spring-barrel and its inner end secured to the shaft G.

H and I are ratchet-Wheels, each being firmly secured to the shaft G'. The shaft G' is secured to the uprights m by means of the boxes d'.

F is a shaft secured to the uprights m above the shaft G' by means of the boxes t'. To the shaft F' are firmly secured the toothed segments P` and N. To one of the uprights m is pivoted by means of the pivot Zt the toothed segment M, which engages with the segment N. The rod D' is pivotally connected at one end to the segment M and at the other end it is connected with the eccentric E' by means of encircling the same. The eccentric E' is firmlysecured to the end of the shaft H'. To the inner side of one of the uprights m is pivotally secured the ratchet W, which engages with the ratchet-wheel H.

Secured to one end of the shaft G' is a toothed wheel R. To the outer side of one of the uprightsm is pivotally secured by means of the pivot e the toothed wheel S, having a shank a', to which the crank T is secured. The wheels R and S engage with each other. The shaft H' is secured to the uprights d by means of the boxes s.

In addition to the eccentric E' there are firmly secured to the shaft II' the drivewheel A, the two sprocket-wheels G, the gearwheel B', and the fly-wheel B. To the inner side of the longitudinal piece t is pivotally secured by means of the pivot t' the gearwheel C, Which engages with the gear-wheel B'. To the inner side of the wheel C is pivotally secured the rod I'. The two sprocketwheels E are connected with the two sprocketwheels G by means of the two sprocketchains C'. The segment P is connected with the ratchet-wheel H by means of the sprocketchain A', which engages with the teeth of the segment and wheel. For convenience in moving the motor is mounted upon wheels K. The power of the motor can be imparted to other machinery byconnecting the same to the motor by means of a belt encircling the drivewheel A. Pumps can be operated by the motor by pivotally connecting the lower end of the rod I' to thepiston-rod of the pump. It is evident if the crank Tbe turned in the proper direction the shaft G' will revolve and wind the springs F attached thereto, and that the ratchet W will prevent the springs from unwinding only as they unwind by revolving the barrels D. It is also apparent that the wheels E, one of which is attached to each barrel, will revolve with the barrels on the shaft G', and that the revolving wheels E will cause by means of the sprocket-chains C and sprocketwheels G the shaft H' and the eccentric and wheels secured thereto to revolve. The revolution of the eccentric E imparts a rocking motion to the segments M, N, and l? by means of the eccentric-rod D', and when the segment ICO P moyems in theqirection that the arrow points it cansk the-1 chinf-A toiV eiigge fiiith "the teeth of the ratchet-Wheel I'I'ai'idievohe the shaft G in the proper direction to Wind the springs F; but when the- Segment P moves in a direction opposite to that to which the arrow points then the ch--i' glidej'o'verfthe teeth of the ratchet-wheel H and does not move the ratchetwheel or shaft., Gi, flhe springs F will not he automatically wound es fast as they unwind; but the motor after the Spririgsm@wuniby turning the @rank T will 'rninuchiongteron"account of its auto-f niatlcaily winding its springsthainjit` ,ot-her-4 wise would.
